Myrtos Beach – Kefalonia/Cephalonia
As waves curve along the beach they also pick up the finest bits of marble; this creates sediment plumes that follow the curve of the beach with the direction of the waves giving the water the most inviting shade of turquoise.

Myrtos has been described as “one of the most dramatic beaches in Greece”, with its “mile-and-a-half long arc of dazzling white pebbles.”
It was used as the location for the mine explosion episode in the film Captain Corelli’s Mandolin ~Wikipedia
